Analysis Of Insulator Cracks And Self-fragmentation Phenomena After Electrical Breakdown

suspension type insulator is made of tempered glass. composite tension insulator surface is under pressure and prestress. If high voltage transmission line insulators cracks or experiences an electrical breakdown, overhead power line insulators will shatter into small pieces. This is often referred to as "self-destruction." When tension insulator is operating, this function does not require a "zero value" check.
